Re: Upside-down
Didn't you see the Ignobel Prize awards last week? One of them was won for experiments in suspeding rhinos upside down by their legs - and it turns out their lungs work just as well as the right way up. And much better than when they're lying on their sides.
I'm surprised their aren't any rhinos in Australia actually. I guess they're probably not dangerous enough to fit in - even though they operate effectively when upside down. The Aussies were probably holding out for the hippos. [cue: Bonnie Tyler - ed]
Anyway, if rhinos can do it, why not submarines? Sharks can manage.
